Answer:

$918.02

Step-by-step explanation:

As each tire costs $213.99, you will be multiplying that by 4:

$213.99*4 = $855.96

Now you will have to add the tax to the price. You will do the following:

$855.96*.0725 = 62.0571

You will round that to $62.06

$855.96+$62.06

The total would be $918.02

Questions:

A clothing manufacturer uses the model a = √(f + 4) - √(36 - f) to estimate the amount of fabric to order from a mill. In the formula, a is the number of apparel items (in hundreds) and f is the number of units of fabric needed. If 400 apparel items will be manufactured , how many units of fabric should be ordered?

Answer:

32 units of fabrics

Step-by-step explanation:

Given

[tex]a = \sqrt{f + 4} - \sqrt{36 - f}[/tex]

Required

Find f when a  = 4

Substitute 4 for a

[tex]4 = \sqrt{f + 4} - \sqrt{36 - f}[/tex]

Rewrite as:

[tex]\sqrt{36 - f} + 4 = \sqrt{f + 4}[/tex]

Square both sides

[tex](\sqrt{36 - f} + 4)^2 = (\sqrt{f + 4})^2[/tex]

[tex](\sqrt{36 - f} + 4)^2 = f + 4[/tex]

[tex]36 - f + 8\sqrt{36 - f} + 16 = f + 4[/tex]

Collect Like Terms

[tex]8\sqrt{36 - f}= f +f+ 4 - 36 -16[/tex]

[tex]8\sqrt{36 - f}= 2f -48[/tex]

Divide through by 2

[tex]4\sqrt{36 - f}= f -24[/tex]

Square both sides

[tex]16(36-f) = (f - 24)^2[/tex]

[tex]16(36-f) = f^2 - 48f + 576[/tex]

[tex]576-16f = f^2 - 48f + 576[/tex]

[tex]-16f = f^2 - 48f[/tex]

Collect like terms

[tex]f^2 - 48f + 16f = 0[/tex]

[tex]f^2 -32f = 0[/tex]

Factorize

[tex]f(f - 32) = 0[/tex]

[tex]f = 0[/tex] or [tex]f = 32[/tex]

f can not be 0 because some units must be ordered.

So, f = 32

Answer:

41.5

Step-by-step explanation:

you use the trigonometric equations. in this case, we will use SOH:

sin 49=opposite/adjacent

sin 49=x/55

55 sin 49=x

41.50=x

Therefore, x is equals to 41.50. And it is already to it's nearest hundredth.

The value of x is  41.25.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

We use the sin function.

Sin 49 = DE/DF

Sin 49 = x / 55

0.75 = x / 55

x = 0.75 x 55

x = 41.25

Thus,

The value of x is  41.25.

Answer:

15.6 inches

Step-by-step explanation:

Here we want to find the length of the missing side

Mathematically, we can use Pythagoras’ theorem

The theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides

Let the missing side be x

18 is the side that faces right angle and this is the hypotenuse

Thus, we have ;

x^2 + 9^2 = 18^2

x^2 = 324 - 81

x^2 = 243

x = √(243)

x = 15.6 in

The value of x assuming e that segments that appear to be tangent are tangent is 8

The triangle inside the circle is right angles since the side length "x" is tangential to the circle.

To determine the value of "x", we will use the Pythagorean theorem as shown:

17^2 = x^2 + 15^2

289 = x^2 - 225
x^2 = 289 - 225
x^2 = 64

x = 8

Hence the value of x assuming e that segments that appear to be tangent are tangent is 8

Answer:

angle k = 72

Step-by-step explanation:

Hey There!

When triangles are similar all of the angles that correspond with each other are congruent ( have the same value)

ex. angle g and angle m are corresponding so they both equal 70

So to find angle K we have to find the value of angle F (because they are corresponding)

So we are given two angles

remember that all angles in a triangle will add up to equal 180

so we subtract the given angles from 180 to find the missing angle

180-38-70=72

so angle F = 72

like stated earlier angle F and angle K are corresponding so if angle F equals 72 then Angle K = 72

2w + 14 + 2w = 54

4w = 40

w = 10

L = 10 + 7 = 17
